CANopenIA-XA by Philips Semiconductors
[ CANopenIA-XA | Direct I/O | Coprocessor ]
The CANopenIA-XA chip provides instant access to CANopen networks. It is a CANopen peripheral chip that can be used with or without a host processor. The chip is configured via an EEPROM, which contents gets generated by a provided setup tool. Read the comparison to see what the main differences are between this implementation and other CANopen implementation methods.
This implementation is based on the Philips 16-bit XA-C37 microcontroller. The CANopen stack was specifically written and highly optimized for this processor to achieve best possible performance.
Operating Modes
The CANopenIA-XA chip supports 2 different operation modes:
- Direct I/O
(formerly mode 1 and mode 2)
No code development required!
In this mode, the CANopenIA-XA can be used directly as a CANopen DS401 Generic I/O compatible input and output node for digital and analog data. The chip supports a total of 20 digital inputs or outputs, 4 high-resolution analog inputs and 2 high-resolution analog outputs. The digital signals are divided into 3 groups of 8, 8 and 4 signals. Each group can be individually selected to be either input or output.
High-resolution, external analog components are connected to the CANopenIA-XA chip via SPI providing the analog I/O channels.
- CANopen Slave Coprocessor
(formerly mode 3)
Code development on existing hardware.
This mode requires a Host processor running the main application. The CANopenIA-XA functions as a CANopen coprocessor. The communication between the Host and the CANopenIA-XA either uses a shared memory or the serial (UART) port. When using shared memory, such as a dual ported RAM, the shared memory contains the entire process image. The process image contains all process data that is transmitted to and received from the CANopen network.
